  • Patent number: 8579197
    Abstract: A solid-state imager is mounted at a point-of-transaction workstation for capturing images of one- and two-dimensional indicia and is operated at high speed to resist image blurring due to relative movement between the target and the imager. Dedicated hardware assistance and computation resources are allocated to decode multiple, continuous and simultaneous video streams from multiple imagers at the workstation.
    Type: Grant

  • Patent number: 7475821
    Abstract: Described is a scanner for reading an optical code which includes a light transmission system and an image acquisition system. The light transmission system projects light on a target. The image acquisition system receives light reflected from the target to generate an image of the target. The image acquisition system is arranged to receive the light reflected from the target at a plurality of angles so that, when specular reflection of the target is associated with a first of the plurality of angles, light from a second one of the plurality of angles is available to minimize image degradation associated with the specular reflection.
